[Yanel-dev] Unset language of user

[Michael Wechner]

Hi

I have introduced

src/core/java/org/wyona/security/core/api/User.java#unsetLanguage()

in order to ... er .. unset the language of a user ;-)

This allows for example to switch back to the browser or realm language, 
instead using
a specific user language such as 'en' or 'de'.

Cheers

Michael
